Click an empty position to place your man.
A move consists of walking across empty positions until you encounter an obstacle. If this obstacle is a coloured square block you must walk onto the block and thereby eliminate it.
In the next move you have to turn 90 degrees (left or right) to either side.

YOU CANNOT LAND ON AN EMPTY POSITION AT THE BORDER!
You are allowed to cross your own path.
Apart from this exception, you cannot step onto a position you have been to before.

Variant 1-23 (fixed setups): YOU HAVE TO ELIMINATE A BLOCK WITH EVERY MOVE

Variant 24-46 (fixed setups): YOU DON'T HAVE TO ELIMINATE A BLOCK WITH EVERY MOVE
There are also several randomized variants attached.

You win if you eliminate as many blocks as given at the top border.
Solutions for variants 1 through 23 have been attached. These solutions have been found by hand; hence you might be able to improve on them.

When SmartMoves is activated, you simply click the target position to move your man. Activate it via View/Options/Board/SmartMoves.

There are also ten randomized variants attached.
